Please excuse my ignorance, but I just saw this article:

http://formen.ign.com/news/16796.html?fromint=1

And it mentions the motor:

The Skyline GTR’s race-tested RB36DETT DOHC, 24 valve 2.6 liter intercooled, twin-turbo I6 at a very conservative 280 base horsepower and a very respectable 289 lb/ft of torque.

This is a typo right? What is the biggest RB motor out there?

By the sounds of the article, they are refering to the RB26DETT so it looks like a typo. No such thing as an RB36DETT.

While we're kind of on the topic, what's the biggest RB engine you could make? e.g. RB30 block, RB26 head etc - no idea what crank and other parts you'd need, but roughly how big could you make one. I realise it would totally change the nature of the engine if it was 3.5L or so, but I'm just kind of curious.

We have tried up to 3.3 litres - we could have gone more, but it was diminishing returns, hence pointless.

Just for completeness, we also went as low as 2.4 litres...

Mario.

I suppose it does make sense that if you're increasing the stroke it wouldn't be as easy to rev as hard. Also, you aren't really increasing the volume of the engine that much % wise once you are adding only a few tenths of a litre.

How did the GTR respond to the reduced capacity? I think it was Nismo that reduced the capacity of a VH45DE to 3.5L and it revved like an F1 car. Your GTR already is a very revvy machine, so it must have been even better at 2.4L. If I remember correctly, you were having trouble shifting at very high revs at some point (my memory is bad, sorry). Did it make shifting harder?

      Leaking Rear Subframe Bushing?

      Yes, I had ordered the spherical bushings at the same time as the rest. I have high hopes for the anti squat reduction kit.

      Make sure you use the spherical bushes** on the lower arms, ifyou do that. ** at least, if not the whole replacement lower arm.

      The tap for coolant flow control will be stuck open. It's not just the air door motor that dies.

      Not really, but the heater box is pretty simple mechanically....if the door is one way the air bypasses the heater core and if it is the other way it goes through it for warm air.  If you are sure the actuator you moved manually is for the heater mix (there would also be one for output air direction) then I'd take the heater box out and see what is happening (you'll have to regass and re-coolant the systems afterwards) BTW pp724 onwards from the GTR workshop manual cover the system in good detail, it is probably worth checking. I think the IAT sensor might be a problem electrically for getting cold (if you got 24 error code not -24 it thinks the incoming air is -50c) and it covers how to test the sensor (although most likely it is either not plugged in or a wire is damaged)
